Objective:
To investigate the trends in incidence and mortality of thyroid cancer in Nantong City, Jiangsu Province from 2013 to 2022, so as to provide a basis for optimizing comprehensive regional prevention and control strategies.
Methods:
Data on incidence and mortality of thyroid cancer in Nantong City from 2013 to 2022 were collected via the Nantong Cancer Registration Reporting System. Crude incidence and mortality were calculated. The Chinese population-standardized incidence and Chinese population-standardized mortality were calculated using the standard age structure from the Fifth National Population Census in 2000. The average annual percent change (AAPC) was used to analyze the trends in incidence and mortality of thyroid cancer across different genders, age groups, and urban-rural areas from 2013 to 2022.
Results:
The crude incidence and Chinese population-standardized incidence in Nantong City rose from 5.79/100 000 and 4.36/100 000 in 2013 to 34.87/100 000 and 30.40/100 000 in 2022, respectively (AAPC=22.226%, 24.139%, both P<0.05). The crude mortality increased from 0.39/100 000 to 1.07/100 000 (AAPC=10.469%, P<0.05), while the trend for Chinese population-standardized mortality was not statistically significant (P>0.05). The Chinese population-standardized incidence and Chinese population-standardized mortality for females were 20.41/100 000 and 0.30/100 000, respectively, which were 3.28 times and 1.50 times those of males. The Chinese population-standardized incidence showed upward trends for both males and females (AAPC=22.840%, 24.592%, both P<0.05), while the trends for Chinese population-standardized mortality were not statistically significant (both P>0.05). From 2013 to 2022, the crude incidence in the age groups of 15-<45, 45-<65, and 65-<85 years, and the crude mortality in the age group of 65-<85 years showed upward trends (AAPC=27.808%, 21.756%, 13.365%, and 8.030%, all P<0.05), while trends in other age groups were not statistically significant (all P>0.05). The Chinese population-standardized incidence in urban areas was 16.96/105, which was 1.40 times that of rural areas. The Chinese population-standardized mortality in rural areas was 0.27/105, which was 1.29 times that of urban areas. From 2013 to 2022, the Chinese population-standardized incidence in both urban and rural areas and Chinese population-standardized mortality in rural areas showed upward trends (AAPC=17.264%, 27.758%, 6.387%, all P<0.05), while trend in Chinese population-standardized mortality in urban areas was not statistically significant (P>0.05).
Conclusions
From 2013 to 2022, the crude incidence, Chinese population-standardized incidence, and crude mortality of thyroid cancer in Nantong City all showed upward trends in the total population, males, and females, while the trend in Chinese population-standardized mortality was stable. There were differences in mortality trends between urban and rural areas: the trend in urban areas was stable, whereas the trend in rural areas was upward.

A 42-year-old male with chest tightness and dyspnea was admitted to the hospital. Chest CT indicated diffuse interstitial lung infiltration. Despite receiving anti-infective therapy, glucocorticoid therapy, and immunosuppressive agents, the patient developed refractory hypoxaemia. Endotracheal intubation and invasive mechanical ventilation failed to improve oxygenation. Therefore the patient was diagnosed with rapidly progressive interstitial lung disease (RP-ILD) accompanied by type Ⅰ respiratory failure. Veno-venous (VV) extracorporeal membrane oxygenation (ECMO) was initiated, and oxygenation improved in this patient. The patient subsequently underwent bilateral lung transplantation with veno-arterio-venous (VAV) ECMO support. ECMO machine was withdrawn on day 1, and extubation was achieved on day 9 after surgery. Histopathology revealed fibrotic nonspecific interstitial pneumonia (NSIP) with hyaline membrane formation. The patient developed ICU-acquired myasthenia and received early rehabilitation, with gradual recovery of muscle strength. During follow-up, graft lung function remained stable. This case demonstrates that ECMO can serve as a bridge to lung transplantation in RP-ILD patients.

ObjectiveTo analyze the comorbidity patterns of chronic metabolic diseases and their influencing factors among residents aged 35‒75 years old in Nantong City of Jiangsu Province, and to provide theoretical support for the prevention and control of comorbidities. MethodsThe permanent residents aged 35‒75 years from the Comprehensive Prevention and Control Project of Cardiovascular and Cerebrovascular Diseases in Nantong City from 2021 to 2024 were selected as the research subjects. Clustering analysis and association rule were used to investigate the comorbidity patterns of chronic metabolic diseases, and their influencing factors were identified through logistic regression analyses. ResultsThe prevalence of comorbidity of chronic metabolic diseases among residents aged 35‒75 years in Nantong City was 47.40%. Among comorbidity patterns based on disease counts, the prevalence of hypertension+dyslipidemia was highest in binary comorbidity patterns (6.25%), while that of hypertension+dyslipidemia+obesity was highest in ternary comorbidity patterns (4.01%). Association rules showed that in both binary and ternary comorbidity patterns, the confidence level was highest for obesity+hypertension (72.70%) and obesity+dyslipidemia+hypertension (74.54%). Renal insufficiency formed an independent cluster in cluster analyses. Logistic regression analyses revealed that, compared with the non-comorbidity group, males (OR=2.22, 95%CI: 1.69‒2.91), advanced age (45‒54 years, OR=1.38, 95%CI: 1.02‒1.88; 55‒64 years, OR=1.59, 95%CI: 1.14‒2.23; 65‒75 years, OR=2.34, 95%CI: 1.58‒3.47), and low physical activity (OR=1.26, 95%CI: 1.10‒1.65) were influencing factors for metabolic disease comorbidity. ConclusionIn the comorbidity patterns of chronic metabolic diseases among residents aged 35‒75 years in Nantong City, hypertension, diabetes mellitus, and dyslipidemia interact with each other. Individuals with obesity are more prone to diseases such as hypertension and dyslipidemia. Prevention and control of chronic metabolic diseases should be strengthened for males, individuals with low physical activity and advanced age.

ObjectiveTo investigate the effects of zinc finger E-box binding homeobox 1 (ZEB1) on the proliferation, migration, and invasion of lung adenocarcinoma H322 cells, as well as its underlying molecular mechanisms. MethodsThe gene expression characteristics of the transcription factor ZEB1 in lung adenocarcinoma were analyzed using data from the GEO and TCGA public databases. RT-qPCR and Western blot were employed to measure mRNA and protein expression levels of ZEB1 in lung adenocarcinoma cell lines (H322, A549, 95-D) and normal human bronchial epithelial cells (BEAS-2B). Lentiviral transduction was utilized to establish stable ZEB1-overexpressing (Oe-ZEB1) and vector control (Oe-NC) H322 cell lines. Cell proliferation was assessed using CCK-8, colony formation, and EdU assays, while apoptosis was evaluated by Hoechst33258/PI double staining. Wound healing and Transwell assays were performed to examine cell migration and invasion capabilities. Cell cycle distribution was determined by flow cytometry, and Western blot was used to analyze protein expression changes in relevant signaling pathways. ResultsThe findings from GEO and TCGA indicated that ZEB1 expression in lung adenocarcinoma varied with tumor malignancy grade. RT-qPCR and Western blot analyses revealed significantly higher ZEB1 expression in lung adenocarcinoma cell lines compared to BEAS-2B cells (P0.05). Results from the CCK-8, colony formation, EdU, wound healing, and Transwell assays demonstrated that, compared with the un-transfected control (Control) group, Oe-ZEB1 H322 cells exhibited enhanced proliferation, migration, and invasion capabilities (P0.05). Hoechst33258/PI double staining and flow cytometry analyses showed that, relative to the Control group, apoptosis was reduced in Oe-ZEB1 H322 cells (P0.05). Additionally, a decreased proportion of cells in the G1 phase and an increased proportion in the S phase were observed in Oe-ZEB1 cells, indicating accelerated cell cycle progression. Western blot analysis further revealed that, compared with the Control group, Oe-ZEB1 H322 cells exhibited upregulated expression of N-cadherin, mutant p53 (mutp53), and Cyclin D1 (P0.05), while expression levels of E-cadherin, murine double minute 2 (MDM2), and p21 were downregulated (P0.05). ConclusionOverexpression of ZEB1 promotes the proliferation, migration, and invasion of lung adenocarcinoma H322 cells and may facilitate cell cycle progression by modulating the MDM2/mutp53/p21 signaling pathway, thereby promoting the transition of cells from the G0/G1 phase to the S phase.

BACKGROUND:Studies have shown that patients with premature ovarian failure have changes in the structure of intestinal flora and that imbalance of intestinal microbiota may be one of the important mechanisms in the development of premature ovarian failure. OBJECTIVE:To investigate the effect of Liuwei Dihuang Wan on oxidative stress and intestinal microbiota in premature ovarian failure mice induced by cyclophosphamide. METHODS:Forty-five female ICR mice were randomized into three groups:blank group(normal mice),model group(premature ovarian failure mice),and Liuwei Dihuang Wan group.A mouse model of premature ovarian failure was prepared by one-time intraperitoneal injection of cyclophosphamide(120 mg/kg)in the latter two groups.After successful modeling,the Liuwei Dihuang Wan group was intragastrically administered for 28 continuous days,and the other two groups were intragastrically administered with the same amount of normal saline for 28 days.Mouse body mass was recorded weekly and ovarian index was calculated.The development of mouse follicles was observed using hematoxylin-eosin staining.ELISA method was used to detect serum levels of anti-Mullerian hormone,estradiol,follicle stimulating hormone,superoxide dismutase,glutathione peroxidase,and malondialdehyde.Meanwhile,the gut microbiome of all mice was detected through 16S rDNA sequencing. RESULTS AND CONCLUSION:The mice in the model group had loose hair,decreased vigor and grip strength,almost no increase in body mass,and decreased ovarian index.Whereas,the mouse body mass and ovarian index were increased after treatment with Liuwei Dihuang Wan(P<0.05).The estrous cycle of mice in the model group was disorganized;Liuwei Dihuang Wan could restore the estrous cycle and reduce the number of atretic follicles in mice with premature ovarian failure.The serum levels of follicle stimulating hormone and malondialdehyde in the model group significantly increased(P<0.01),while the levels of estradiol,anti-Mullerian hormone,superoxide dismutase,and glutathione peroxidase significantly decreased(P<0.01).Liuwei Dihuang Wan could significantly decrease the serum levels of follicle stimulating hormone and malondialdehyde(P<0.01),and increase the levels of estradiol,anti-Mullerian hormone,superoxide dismutase,and glutathione peroxidase.According to the 16S rDNA sequencing results,Liuwei Dihuang Wan could regulate the abundance and diversity of intestinal microbiota,and increase the relative abundance of beneficial bacteria.KEGG pathway analysis showed that the intestinal microbiota and metabolic pathways,biosynthesis of secondary metabolites,microbial metabolism in different environments,and biosynthesis of amino acids were regulated by Liuwei Dihuang Wan.To conclude,the changes in the structure of intestinal microbiome may be one of the potential mechanisms of Liuwei Dihuang Wan in treating premature ovarian failure.Liuwei Dihuang Wan can regulate the structure of intestinal microbiome,increase the number of beneficial bacteria,reduce the number of harmful bacteria,and thus improve the balance of intestinal microbiota.This regulatory effect helps to reduce oxidative stress levels and further inhibit ovarian oxidative stress in mice with premature ovarian failure.
